Nasopharyngeal Carcinoma

Abstract

The nasopharynx is a cubodial chamber that is posteriorly bound by the C1–C2 vertebral body and sphenoid bone. Anteriorly, it connects with the nasal cavity and begins at the posterior choanae. Inferiorly, it connects with the oropharynx and the superior surface of the soft palate forms the floor of the cavity (Fig. 1a).
